During my undergrad university days (at the University of Utah), I took some Mandarin classes. There was a local Confucius Institute which provided various free materials in Chinese to the campus library. The extent of my direct contact with them was receiving a couple hundred dollars for doing well in a Mandarin speech contest they held for my class. It was obvious that there was a certain propaganda aspect to this…
Not saying that there isn't necessarily any attempt at propaganda there, but it sounds like you're just saying that these resources didn't directly criticize the CCP. Seems to me like it would be a bigger deal if learning materials did start going into the negatives of a ruling government. It would be a little odd if French materials for learning English included a denunciation of the actions of the British Empire or the Bush Administration for example (even if the denunciation was deserved).
What kind of negative things would you expect a more even-handed textbook for learning Chinese to go into?
